I am thrilled to share our work on NAD metabolism in gut microbiome published today! A collaborative work between @BaurLab and Rabinowitz lab @dr_ohsopretty

Chellappa et al. show that the gut microbiome primarily obtains its NAD from host-derived circulating nicotinamide. Deamidation of nicotinamide to nicotinic acid by microbes maintains circulating...

My lab’s 5-year NIH R01 grant, awarded to study gene therapy for hearing loss, was abruptly terminated. I want to share how this action has been incredibly harmful and disruptive, not just to my lab, but to the scientific process itself. 1/15

More than 98% of families in this country choose to vaccinate their young children. But now, vaccine policy is being shaped by the small, extreme minority that doesn’t. This decision doesn’t reflect, protect or support families.

RFK Jr. went on national TV and spouted egregious, dangerous falsehoods about vaccines. As a parent and infectious diseases doctor, I couldn't stay silent. @FoxNews might not fact-check him, but I will. I've reviewed the trials. I've catalogued them. I have receipts. 🧵

Federal science cuts aren’t just halting medical research or disrupting clinical trials. They are already costing us $8.1 billion and 35,000 jobs. The projected loss is $16 billion and 68,000 jobs every year. This reaches every corner of America.

Powerful piece on the dominance of NIH-funded science and its role in drug discovery. Cutting the NIH budget puts all the U.S. has built at risk. We urge @RFKJr_Official & @NIHDirector_Jay to champion U.S. science and defend NIH funding https://t.co/2Bz8s3URSb via @statnews

BREAKING: In a stunning moment, a meteorologist from Southern Florida just announced that he will not be able to accurately tell his audience the weather due to massive DOGE cuts. This is terrible and dangerous.

BREAKING: Condoleezza Rice just went on Fox & Friends and dismantled Trump’s war on universities and scientific research. When even Bush’s Secretary of State is side-eyeing your assault on knowledge and education, you’ve officially crossed into uncharted stupidity. This isn’t

Amazing to see so many Republican House members acting surprised about what was in the bill they all voted for. They are lying. They hoped we wouldn't notice.

Pretty impressive work by the Republican House to pass a budget bill that both takes health insurance away from 10.9 million people AND increases the national debt by 2.4 trillion dollars. Today’s GOP: less health and more debt!

Folks, I won’t sugarcoat it. This is gravely concerning. Leaked internal reports indicate that FEMA is just not ready for hurricane season. I am demanding answers. We don’t have time to waste on this.

We just got word that the Republican budget bill - the one that throws 15 million people off their health care - will also add $2.4 TRILLION to the national debt. That's more than the entire annual GDP of Canada. I want to explain to you why this matters.

Harvard researcher Dr Sarah Fortune was only two years away from creating a vaccine that could have saved the 1.25 million people killed each year by tuberculosis. But last month, she received a letter telling her that the $60 million grant funding her research was being halted

Without a doubt, the spread of scientific mis/disinformation may be one of the most serious public health threats of our time.

Case in point, mate. Your assertion is simply untrue, it’s false. This is a disinformation talking point from antivaccine groups, their wellness/influencer/supplement financiers and their political allies
@jsm2334 @ChildrensHD @PeterHotez Naw mate. Had I been informed there were bits of chopped up aborted babies in the vax I would NEVER have taken it. No hesitation at all. Just a straight NO!
